CHAIR.

Specification of Letters Patent.

Patented Nov. 13, 1906.

' Application filed September 26, 1906. Serial No. 280,186.

To all whom it may concern.-

Be it known that 1, JAMES L. NEWELL, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Chairs, of which the following is a specification.

This invention relates to improvements in chairs; and it consists of the novel features hereinafter described and claimed.

The object of my invention is to construct a chair to be supported on a single leg and pivotally mounted to the base of a table and having its seat slidably and revolubly mounted to the leg, whereby the same may be tilted against the table when not in use.

A further object of my invention is to construct a chair having the seat portion slidably and revolubly mounted on a single leg and provided with means whereby the seat portion is locked to the leg when in a tilted position and also to prevent the seat from revolving completely around on the leg, which devices act to prevent the back of the chair from coming in contact with the tabletop.

In the drawings, Figure 1 is a side elevation of my invention, showing it attached to the base of a table and in relative position with the table. Fig. 2 is a detail per spective view of the seat-supporting device. Fig. 3 is a detail plan view of a portion of the seat-supporting device and of the leg with parts broken away,showing the po sition of the stops. Fig. 4 is a side elevation of my invention withparts broken away, showing the connection between the seatsupporting device and the leg. Fig. 5 is a detail perspective view of the leg. Fig. 6 is a side elevation of-the lower portion of the leg with a part broken away, showing a modified form of stop made use of for locking the leg when in tilted position.

Inthe construction of the device as shown I provide a casting 7, composed of two vertical skeleton frames 8, connected at the bottom by integral cross-pieces 9 and 10. The cross-piece 10 is provided onits under side with a trunnion 11, having on its upper and lower ends collars 12 and 13. The surfaces of these collars are constructed perfectly smooth and fit into the socket 14, formed in the upper end 15 of the leg 16. To each side of the frames 8 and extending laterally from the cross-piece 10 is a lug 17, which is designed to come in contact with the projection 18, formed on the arm 19, which projects from the upper end 15 of the leg. Between are also provided with stiffening-braces 2,5.

The bracket 24 is constructed shorter than the bracket'23, and the supporting-surfaces 26 of each of said brackets are inclined to support the chair-seat 27, causing the front end of the chair-seat to be raised somewhat higher than the rear. (See Figs. 1 and 4.) The sliding frame is supported between the frames 8 by means of the bolts 28 and are so ground and fitted as to make a tight yet movable fit, so that the sliding member may operate within the frame freely without oscillation and to prevent rattling. In each of the brackets 23 and 24 is formed a bore 29, in which is located a rubber bufier 30, which is in alinement with the bolts 28 and adapted to come in contact therewith when the sliding member is either brought forward or backward without j olting the same.

Referring to the upper end of the leg 16, the projecting arm 19 is provided with two vertical projections 31, forming between them a recess 32, being tapered in form, and which is to receive the downwardly-projecting tapering lug 33, formed on the rear end of the sliding frame 20. The object of this lug and recess is to lock the chair member to the leg when the same is in a tilted position and to prevent the chair from being revolved while in this position and cause the back of said chair to come in contact with and dent the table-top.

The lower end 34 of the leg 16 is provided with a heel 35 and a hinge member 36, the hinge member 36 being supported between ears 37, formed on the base 38 of the table and hingedly secured therein by a bolt 39. On the front face of the hinge member 36 is formed a projecting lug 40, which is so shaped and formed at an angle as to come in contact with the upper surface of the base 38 when the said leg is in tilted position for locking the same.

A spring 41 is located to the rear of the hinge member 36, (see Fig. 4,) the ends of said spring being connected to the base, while a portion of said spring is bent and brought in contact with the lower edge of the leg and has suflicient resiliency to automatically tilt the chair as soon as the person has contact with the table-top, as previously removed. The automatic tilting of the device will cause the chair portion, by means of its sliding member, to move toward the tablepedestal and cause the lug 33 to enter the recess 32 and lock the same.

If a person is in position upon the chair and desires to revolve sidewise, the chair will permit this operation by means of the trunnion 11 until the lugs 17 come in contact with the shoulder 18, and thus prevent further movement. The purpose of this is also to prevent the back of the chair from coming in mentioned.

By referring to Fig. 6 I have devised a modified form of limiting the tilting motion of the leg. This is done by removing the lug 40 from the hinge member and forming therein a recess 42. I then place in the base a bolt 43, having a one-sided head 44, which is located in the recess, and when the leg is tilted by the action of the spring 41 the surface 45 comes in contact with the head 44 of the bolt and stops the same. The purpose of this modified form is in the event that in shipping a number of devices the legs can be folded close to the pedestal of the table by simply removing from the base the bolt 43.

A chair of this character horizontally mounted to the base of a pedestal-table has been found to be preferable in cases where it is desired to utilize space to prevent the chairs from being promiscuously carried around the room; but such a device has been especially designed for use in steamships, dining-cars, or any place where it is desired to retain the chairs and table in position.

Having thus described my invention, what I claim as new, and desire to have secured to me by the grant of Letters Patent, is-

1'. A chair of the character described comprising a leg hingedly mounted to the base of the table, a sliding member pivotally located on the upper end of said leg, stops formed on said sliding member and on the upper end of the leg to limit the side motion of the chairseat and to lock the same when in tilted posig tion, substantially as specified.

2. A chair of the character described, comprising a leg pivotally supported to a tablebase, a socket formed in the upper end of the leg, an arm projecting from said socket and provided with a recess, a revolving member, a trunnion carried by said revolving member and located within the socket, a sliding member located within the revolving member, a lug formed on the sliding member to come in contact with the recess formed in the arm projecting from the socket whereby the same is locked when the leg is in a tilted position,

' substantially as specified.

3. A chair of the character described comprising a sliding member, on which is supported the chair-seat, a revolving member supporting the sliding member, a trunnion formed on the revolving member, on which the chair is adapted to revolve, a leg pivotally mounted to the base of the table, a'

socket formed in said leg to receive the trunnion of the revolving member, locking devices for locking the sliding member to the leg to prevent side movement when in tilted position, lugs formed on the revolving member projections formed on the leg, to limit the side motion of the chair, and a means whereby the tilted position of the leg is limited,

substantially as specified.

4. A chair of the character described, comprising a single leg pivotally secured to a table-base, a combined sliding and revolving member supporting the chair-seat carried in a socket in said leg, a locking device whereby the seat of the chair is locked to prevent side motion when in tilted position, lugs formed on the revolving member, projections formed on the leg for limiting the side motion of the seat when in horizontal position, a spring for automatically tilting the chair against the table, and lugs to limit the tilting of the device, substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
